As recently reported by columnist Nicholas Carr, if you have a smart phone, you'll likely be "consulting the glossy little rectangle nearly 30,000 times over the coming year."
Most of us don't think that's too awful. I certainly depend on mine…and all the time. It's become my phone, my mailbox, my knowledge bank, my companion, my navigator, my weather channel, to name just a few of the wonderful conveniences of this remarkable nano-technology. But, here's the rub. Accordingly to Mr. Carr, there are numerous research studies that, as the headline above suggests, indicate that smart phone access is harmful, well, to one's intellectual, emotional, and perhaps even bodily health.
Let me just share a few of the cited studies from Mr. Carr's article on "How Smart-phones Hijack Our Minds." https://www.wsj.com/articles/how-smartphones-hijack-our-minds-1507307811?mod=e2tw
First, as reported by Mr. Carr, there's a California study that suggests that the mere presence of smart phones hampers our intellectual problem-solving abilities. In the study of 520 undergraduate students, the researches – using a TED lecture talk – tested students on their exam performance based on their understanding of the lecture with the students divided into three separate groups. In one classroom, the students placed their cellphones in front of them during the lecture and the subsequent exam. In another classroom the students had to stow their cellphones so that they didn't have immediate access (i.e., sort of an "out-of-sight–out-of-mind" approach). In the last classroom situation, the students had to leave their cellphones in a different room from the lecture hall. Almost all of the students reported that the placement or access of their cell phones did not compromise their exam performance in anyway. But, the test results shockingly indicated otherwise. The students with cellphones on their desks performed the worst on the exam. In addition, even the students with the cellphones stowed performed not nearly as good as the students who were not permitted to bring cellphones to the lecture. Apparently, just the knowledge that one's cellphone is ready and standing by negatively impacts learning.
Second, also as reported by Mr. Carr, there's a Arkansas study that suggests that students can improve their exam performance by a whole letter grade merely by leaving one's cellphone behind when headed to classes. In that study of 160 students, the researchers found that those students who had their phones with them in a lecture class, even if they did not access or use them, performed substantially worse than those students that abandoned their cellphones prior to class, based on test results on cognitive understanding of the lecture material. In other words, regardless of whether one uses one's cellphone during class, classroom learning appears to be compromised just with the presence of one's cellphone.
Third, as again reported by Mr. Carr, cellphone access or proximity not only hinders learning but also harms social communication and interpersonal skills. In this United Kingdom study, researches divided people into pairs and asked them to have a 10-minute conversation. Some pairs of conversationalists were placed into a room in which there was a cellphone present. The other pairs were placed in rooms in which there were no cell phones available. The participants were then given tests to measure the depth of the conversation that the subjects experienced based on measures of affinity, trust, and empathy. The researches found that the mere presence of cellphones in the conversational setting harmed interpersonal skills such as empathy, closeness, and trust, and the results were most harmful when the topics discussed were "personally meaningful topic[s]." In sum, two-way conversations aren't necessary two-way when a cellphone is involved, even if it is not used.
Finally, Mr. Carr shares research out of Columbia University that suggests that our trust in smartphones and indeed the internet compromises our memorization abilities. In that study, the researches had participants type out the facts surrounding a noteworthy news event with one set of participants being told that what they typed would be captured by the computer while the other set of subjects were told that the facts would be immediately erased from the computer. The researchers then tested the participants abilities to accurately recall the factual events. Those that trusted in the computer for recall had much more difficulty recalling the facts than those who were told that they couldn't rely on the computer to retain the information. In other words, just the thought that our computers will accurately record our notes for later use, might harm our abilities to recall and access information. And, as Mr. Carr suggests, "only by encoding information in our biological memory can we weave the rich intellectual associations that form the essence of personal knowledge and give rise to critical and conceptual thinking. No matter how much information swirls around us, the less well-stocked our memory, the less we have to think with."
Plainly, that's a lot to think about. And, with all of the conversations swirling about as to whether teachers should ban laptops from classrooms, it might just add "fuel to the fire." On that question, this article does not opine. But, regardless of whether you take notes on a computer or not, according to the research, there's an easy way to raise your letter grade by one grade. Just leave your smartphone at home, at your apartment, or in your locker…whenever you go to classes. (Scott Johns).
